I own a few of his pendants and they are powerful. Orgonite will not reduce emf only change the nature of it into something that is less harmful to the body. The theory is orgonite transmutes negative energy into something more positive: Here’s a little about how Orgone Matrix Material works:

Orgonite is primarily made from metals chips (Copper, Brass, Aluminum curls & etc), polyester resin (fiberglass resin) and a quartz crystal.

These devices are not like the old orgone accumulators, which accumulate orgone, irrespective of it being negative or positive. Orgonite however, works continuously to transmute or process negative orgone/chi/qi or other energies into positive form only

Organic substances attract and hold Scalar / Orgone charge, while metallic substances tend to repel it. Basically, Orgonite pulls in the Bioenergy, and while the energy is inside the device, The metal particles and organic resin both push and pull on it in all directions at the same time. This puts friction on the energy. The friction is great enough at many small points within the matrix to cause the energy to shift upwards in spectrum to Aether, so that it temporarily ceases to exist as a part of the electromagnetic spectrum. When the energy comes back out of the device, it collapses back into an organized, defined state and comes into existence as bioenergy / magnetism.

Quantum physicists have discovered that subatomic particles pop in and out of existence as they shift state back and forth between the states of matter and Aether. The same effects take place with waved energies in the electromagnetic spectrum. Different forms of energy appear and disappear as they shift in spectrum back and forth between Aether and lower spectral forms of energy. In the case of a TB, because of the density, when the bioenergy appears again, it has lost the radionic data it was carrying, the wave patterns it was carrying. Those wave patterns are a large part of what makes the bioenergy “healthy” or “unhealthy” for you and other life forms. This same Aetheric flux within the Orgonite has the effect not only of changing Bioenergy from one form to another, but also the property of ‘generating’ Bioenergy when stimulated by other kinds of energy... like light, sound, physical motion, or electricity.

Orgonite can change DOR (harmful Bioenergy) to OR (Healthy Bioenergy). When energy percolates through the matrix, it is in effect reduced to its component polarities. It is then recombined and emitted. The act of being broken down into its positive and negative charges and recombined has the effect of restoring the orgone to a ‘base’ state. Unless a specific wave pattern is impressed on it within the device, it comes out of the Orgone Matrix Material as more or less undifferentiated Bioenergy. When the energy exits the material, the conditions which 'force' it to exist in an undefined state no longer exist, and so it collapses back into a defined state, and is 'colored' (impressed with a Bioenergy wave pattern) to varying degree by the exact composition of the matrix material.

Many devices which employ Orgonite Matrix Material function as Bioenergy Generators, But Orgonite does not actually generate Bioenergy, in the truest sense of the word. Orgonite, when excited with other forms of energy, both converts a portion of the energy used to excite it into bioenergy, and draws additional energy from the Aether, and releases it as Bioenergy. Having understood this, for practical intents and purposes, it can be said that Orgonite 'Generates Orgone’ on demand when excited by scalar waves, magnetic fields, heat, sound, light, electrical energy, kinetic energy, and bioenergy.
